Obviously I'm new in this game, so I need to ask a question. I was watching a few gold specs at market close (HWK, DEG, DRE, MCT). They all got sold down right at the end, which wiped away any gains from the rest of the day. Why is that? Why wait until the last second? Is it because some brokers don't want to hold over night and reduce risk, so they become desperate to sell last minute, or is it to scare retail holderss out of their stocks the next morning, or both?
